How to save the link from the old site?

Question

HTML

Hello. There is a small old wordpress site. It was decided to develop a new one, but on pure html, css, js. In this case, the page URLs look like "* .html" , while on the old site the links look like "*" .
On Habré there is a solution to the problem through .htaccess.

RewriteEngine On
RewriteCond %{REQUEST_URI} ! \.html$
RewriteCond %{REQUEST_URI} ! /$
RewriteRule ^(.*)$ $1.html

The question is, will the site lose its position in the search?

Answer 1

The loss will be but not big if there is a page redirect
